PsyChip/machina ? reverse-engineered prompt

Build me a simple AI powered video surveillance app for a webcam, IP camera, or video file. It should watch the feed in real time, detect and track common objects like people and vehicles, and let me record video or save screenshots with one key press.

I want it to feel easy to use, with zoom and pan controls, fullscreen, several quick resolution presets, and a way to skip frames when I need better performance. It should also remember my settings between launches, like window position, resolution, and processing speed, and handle multiple webcams if more than one is connected.

Please include an instant replay mode with a short rolling buffer, a basic crowd or cluster detection feature, and an optional more accurate mode for tougher scenes. Make the interface responsive and practical, and if you need current docs for camera or model setup, look them up online.
